The day is worked out before breakfast
Djok summarises the night, then sets the day's macronutrient target in grams, based on body weight, the planned training load and the temperature.
Private beta
Djok is an artificial intelligence coach. It reads every second recorded during a ride, namely power, heart rate and cadence, along with sleep and heart rate variability. From that it derives the day's nutrition and training, for cycling as well as running.

Djok summarises the night, then sets the day's macronutrient target in grams, based on body weight, the planned training load and the temperature.
Amounts consumed are entered through the day, and the counters go down accordingly. Barcode, photo or plain text: recognition only proposes a list, which the athlete corrects to the gram, and nothing is recorded without that step. Every line shows where its figure comes from — packaging, photo or estimate — and drinks are counted in millilitres. The entry belongs to the athlete. A second tab shows the micronutrients — iron, magnesium, vitamins, omega-3 — averaged over the last few days, always as minimums: the database knows nothing about the micros of scanned products, and the table says so rather than showing a zero.
Djok builds them from measured weaknesses and the freshness of the day, then adds them to its calendar once the proposal has been accepted. The app runs them and controls the smart trainer. Nothing is added before that agreement.
Difference from the previous best effort, power-to-weight ratio, best performances over six weeks, three months and the season. These are verifiable values, not congratulations.
Two weeks carrying the same load can be thirty hours of base or eight hours at threshold. Djok splits training load by effort type — recovery, endurance, tempo, threshold, VO2max, anaerobic — from second-by-second power, and shows what the total leaves out: an effort can account for eight per cent of the time and a third of the load.
And when it landed: from seven days to your whole history, every period keeps its place on the timeline — a rest week shows up instead of vanishing between the two around it.
Power, weight or preparing for an event: Djok reports progress from the recorded starting value, along with the volume still to be completed in the current week.
When heart rate variability falls, sleep grows short and form declines, Djok combines these signals and warns before the session too many is completed.
The coach answers inside the app, with the athlete's own measurements at hand and a library of referenced scientific papers. When a question is too vague to have a single right answer, it asks for a clarification instead of guessing — feeling tired reads quite differently depending on whether the subject is sleep, training load or nutrition.
A ride can be shared through a link that Djok deliberately keeps short-lived : it expires after 24 hours. The page shows the route, distance, duration, elevation gain and averages — with the track trimmed by 200 metres at both start and finish, so that the athlete's home does not appear on it. It shows neither the session analysis, nor the perceived effort, nor the threshold power.
The artificial intelligence writes the guidance and explains the reasoning. The numbers themselves do not come from it: records, training load and the day's requirements are computed by the software from the recorded measurements, and give the same result every time. When a measurement is missing, Djok says so rather than estimating it.
